The so-called pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the process of drug synthesis. This kind of chemical product does not require a pharmaceutical production license and can be produced in an ordinary chemical plant. As long as it reaches a certain level, it can be used for the synthesis of pharmaceuticals.
Our country needs more than 2,000 kinds of raw materials and intermediates for chemical industry every year, and the demand is over 2.5 million tons. After more than 30 years of development, the chemical raw materials and intermediates required for the country's pharmaceutical production can basically be matched, and only a small part of it needs to be imported. Moreover, due to my country's abundant resources and low raw material prices, many intermediates have been exported in large quantities.
On the one hand, product updates in this field are fast. Generally, after a product has been on the market for 3 to 5 years, its profit margin will drop significantly. This forces companies to continuously develop new products or continuously improve production processes in order to maintain a high production profit; on the other hand, due to the production profit of pharmaceutical intermediates Higher than chemical products, the production process of the two is basically the same, so more and more small chemical companies have joined the ranks of producing pharmaceutical intermediates.

Cam Follower Bearings are also referred to as track follower. They are designed to follow a sliding or rotating piece (cam) and they use rollers or needles as the rolling elements. Cam Follower Bearings are therefore able to replicate a specific motion because they are highly versatile. They have thick-walled outer rings that run on a track. They are used to minimize distortion and bending stress while facilitating high load carrying capacity.Generally speaking, cam follower bearings are designed in different configurations and special structures can be designed according to the task requirements. 
Stud Style
Stud style cam follower bearing has one end plate integrated into the inner race (stud) and the other pressed onto the stud unto a shoulder on the inner race. Both ends of the stud have holes for lubrication and the inner race is induction hardened to maintain some degree of softness in case some modification is required.

Materials of cam follower bearings
Needle roller: Gcr15, quench-hardening HRC60-65
Rings:Gcr15
Cage:Low-carbon steel or reinforced nylon
Both the stud and yoke cam followers have an outer diameter that may either be cylindrical or crowned. The crowned. The crowned ones are often used in turntable type applications because they help reduce skidding.
Â
Feature
Â
- Smaller cross-section leading to greated rigidity,higher load-carrying capacity &Â lower inertia of the needle roller bearings help size and weight reductions in machinery.
Â
- Though they are less wide,their load carrying capacity is high and is most suitable for applications where the load is high &Â the radial space is less.
Â
- Needle roller bearings,which are designed to withstand oscillation can operate under severe conditions &Â interchange with sliding bearings.
Â

Method of extending the bearing's lifetime:
1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.
 Â
2. Don't allow strong impact, such as hammer striking, transfer roller pressureÂ
Â
3. Use the accurate installation tool, avoid to use cloth kind and short fibers
 Â
4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer
 Â
5. General inspection, such as the surrounding temperature, vibrate, noise inspection
Â
6. Keep bearing cleaning from dirt, dust, pollutant, moisture.
Â
7. Bearing should not be ultra cooled.
